High-purity fused silica materials with ultra-low thermal expansion for furnace linings, castables, ramming masses and refractory bricks.
Fused Silica is an amorphous silica material characterized by extremely low thermal expansion, excellent thermal shock resistance, and high refractoriness. These properties make Fused Silica A Grade and B Grade essential raw materials in modern refractory systems operating under severe thermal cycling conditions.
Both grades are widely used in iron & steel, non-ferrous metallurgy, foundries, glass and ceramic industries.
Recommended for high-performance refractories where maximum purity, minimal impurities and extreme thermal stability are required.
View A Grade DetailsA cost-effective and reliable solution for standard refractory applications, offering excellent thermal shock resistance and stable performance.
View B Grade DetailsFused Silica A and B Grade are widely used in the following refractory products:
For iron and steel industries
For induction furnaces
Refractory brick applications
For non-ferrous metal runners
Castables and blocks
For cyclic heating applications
Their low expansion behavior significantly reduces cracking, spalling and lining failure.
Minimizes internal stress during rapid heating and cooling cycles, ensuring dimensional stability throughout service life.
Ideal for furnaces subjected to frequent start-stop operations and rapid temperature fluctuations.
Strong resistance to acid and chemical erosion in aggressive industrial environments.
Suitable for continuous service at elevated temperatures with sustained performance.
These advantages improve furnace life, operational safety, and maintenance efficiency.
